Richardson is a complete hero. A pacifist he refused to fight in WW1. But went as an ambulance driver. There he spent years calculating by hand the first ever mathematical weather forecast. It was based on a day years earlier there was quite precise measurements for. Once nearly losing the calculations under a pile of hay when he had to evacuate. The result came out wrong due to a dampening factor that was needed. But he published anyway and laid the foundations of modern weather forecasting.
